I have a simple shell script that loops through a text file.
There is one value on each line I use to delete a specific folder.

The part I'm missing how to do it remove that line from the text file.


So basically....loop through the text file and remove the line after using it to be a variable of a command.

cheers

Something like this should do:

Code:
while read cur_line
do
        folder=`echo $cur_line | awk '{print $2}'`
        echo Currently deleting $folder...
        sed "/$cur_line/d" yourfile> tempfile
        mv tempfile yourfile
done < yourfile

I don't know what you're using to find the folder-to-be-deleted's name on the current line, but I set it up to be the second field in the current line using that awk statement in the while loop. If you need help, just post again and I'll clarify...

Basically, use sed to delete the line from the file, then output it to a temp file, then move that temp file back to the name of your file.

To be a bit more abstract, the answer is that there is no really simple way to delete just one line from a file. You have to copy all the other lines into a new file, and then replace the old file with the new one.
